Facebook: How active, fun and connected can turn shallow, creepy and obsessive

Tima Chansanchai, communications consultant: "For me, Facebook is a convenient one-stop publishing platform for both personal and professional contacts. I use it to not only promote the work I'm doing, but also organizations I belong to, such as the Asian American Journalists Association. . . . I didn't get on until late 2007, and then, when I did, I got it -- quickly. I made it a point to only 'friend' those whom I've met in person or had conversations with."
